A fuzzy set based tutoring system for adaptive learning

Abstract

This paper proposes a web-based adaptive tutoring system based on fuzzy set that provides learning materials and questions dynamically according to students' knowledge state and gives advices for the learning after an evaluation. For this, we construct a fuzzy level set considering the importance degree of learning goals, the difficulty degree of learning materials, and the relation degree between learning goals and learning materials. Using the fuzzy level set, our system offers learning materials and questions adapted to individual students. Moreover, a result of the test is evaluated with fuzzy linguistic variable. © Springer-Verlag 2004.
